...Oh, wait! Since you're capable of undersea operation, I reviewed some combat records and attempted to put together a light barrier that wards off the effects of nervous impairment. It's very experimental, since Iberian technology is really complicated for some reason? And besides that it wasn't really testable, so don't rely on it to win you any fights with anything you encounter living underwater! It's exclusively to buy you time to run, and it can also double as a floodlight.
